Summary
Highlights
This video is part two of a presentation focusing on the simulation process of a polygraph examination, building upon the previous video which discussed the improvised polygraph machine and its components.
The subject must undergo a pre-examination interview where the polygraph examination process is thoroughly explained for optimal understanding. The tester needs to be knowledgeable about the incident. The subject should be informed that all questions will be answerable with 'yes' or 'no', and that they should not be apprehensive, as any deceit will be reflected in the test results. Questions are categorized into irrelevant, relevant, and control questions.
Before conducting the test, the polygraph examiner must observe several procedures: appraise the subject's basic constitutional rights, obtain their consent, gather operational data, evaluate their psychological preparation, determine their suitability for the test, and inform them of their involvement with the case.
A simulation of a polygraph examination is conducted, where the examiner explains that the test is voluntary and that devices will be attached to the subject's body. The subject is then asked a series of 'yes' or 'no' questions covering personal information, potential nervousness, and past actions like purchasing or selling illegal drugs, stealing, drinking alcohol, school absenteeism due to drinking, providing alcohol to minors, and criminal history.
